49179-00451 Turbocharger for Caterpillar E200B Mitsubishi S6KT Engine

The 49179-00451 turbocharger is supplied for Caterpillar E200B excavator repair with Mitsubishi S6K / S6KT diesel engine applications.

Key Checking Points Before Order

Turbochargers should not be confirmed only by excavator model. The same machine model may use different engine versions or turbocharger specifications, so the old turbocharger plate number and engine model should be checked before quotation.

Part Number Check: Confirm 49179-00451 from the old turbocharger plate, supplier record or removed sample.

Cross Number Check: If the buyer provides 5I-5015 or 49179-00450, confirm it together with engine model and turbo photos.

Engine Check: Confirm whether the engine is Mitsubishi S6K or S6KT.

Machine Check: Confirm Caterpillar E200B application if the turbo is ordered by machine model.

Sample Check: Provide photos of the old turbocharger from the compressor side, turbine side, actuator side and nameplate side.

Turbocharger Replacement Notes

Before replacing the 49179-00451 turbocharger, the engine air intake system, exhaust manifold, oil feed line, oil return line and air filter condition should be checked. Turbocharger failure can be caused by oil starvation, dirty oil, air restriction, exhaust leakage or foreign object damage.

After installation, the lubrication system should be primed before engine start. The oil line should be clean, the air intake pipe should be free from debris, and the engine should be checked for abnormal smoke, oil leakage, boost pressure loss or unusual noise during testing.
